Definitions

  • the present invention relates to a wireless communication system, and more particularly to a data transmission method using packet aggregation in order to improve resource efficiency in a multi-carrier based wireless communication system.
  • a communication system uses a hierarchical frame structure in order to efficiently transmit data of an upper layer.
  • a wireless communication standard such as an Institute of Electrical and Electronics Engineers (IEEE) 802. 11 standard and an IEEE 802. 16 standard has conducted research and development for frame aggregation in a Media Access Control (MAC) layer and a physical (PHY) layer in order to maximize the efficiency of radio resources.
  • IEEE Institute of Electrical and Electronics Engineers
  • IEEE 802. 16 has conducted research and development for frame aggregation in a Media Access Control (MAC) layer and a physical (PHY) layer in order to maximize the efficiency of radio resources.
  • MAC Media Access Control
  • PHY physical
  • FIG. 1 illustrates a general framing process in a wireless communication system.
  • a MAC layer receives a MAC Service Data Unit (MSDU) 110 and attaches a MAC header 111 to the MSDU 110, thereby constructing a MAC Protocol Data Unit (MPDU) 11.
  • the MAC header 111 includes various information such as Source Addresses (SAs) and Destination Addresses (DAs).
  • SAs Source Addresses
  • DAs Destination Addresses
  • the MSDU 110 may be classified according to traffic characteristics and identified by Traffic Identifiers (TIDs).
  • the MPDU 11 is a PHY Service Data Unit (PSDU) 120 and is transferred to a PHY layer. Then, a PHY header 121 is attached to the PSDU 120, so that a PHY Protocol Data Unit (PPDU) 12 is constructed.

  • PPDU PHY Protocol Data Unit
  • the PHY header 121 includes parameters for determining a transmission scheme including a modulation and coding scheme, etc.
  • a preamble 131 including channel estimation and synchronization information is attached to the PPDU 130.
  • a data aggregation method may include an MSDU aggregation method and an MPDU aggregation method.
  • FIG. 2 illustrates the conventional MSDU aggregation method, in which MSDUs 210, 220 and 230 having the same DA 1 and TID1 construct an MPDU 21, an MPDU 22 and an MPDU 23, respectively, together with each MAC header 215.
  • This scheme has a greater effect when traffic of a specific connection session is very bursty.
  • buffering is required until a predetermined number of MSDUs are accumulated. Therefore, it is difficult to apply this scheme to real-time traffic because jitter and delay variation increase.
  • this scheme can achieve a good effect when short packets are aggregated.
  • an MPDU generally has a maximum length within 2000 to 3000 bytes, this scheme has reduced performance when long packets are aggregated.
  • FIG. 3 illustrates the conventional MPDU aggregation method.
  • DAs 315, 325 and 335 and TIDs 310, 320 and 330 are different from each other, but MPDUs 31, 32 and 33 having various DAs can construct and transmit one PPDU 130.
  • the MPDU aggregation method is mainly effective in an Access Point (AP).
  • AP Access Point
  • transmittable MPDUs are aggregated regardless of DAs and TIDs the instant a transmission opportunity is obtained, it does not influence jitter and delay time.
  • the present invention has been made to solve the above-mentioned problems occurring in the prior art.

  • the second transmission unit includes one physical (PHY) header having the destination address.
  • MAC Media Access Control
  • PHY physical
  • the frame includes a frame header having information for a modulation scheme and a transmission scheme

  • the second transmission unit includes a PHY Protocol Data Unit (PPDU).
  • MSDU MAC Service Data Unit
  • MPDU MAC Protocol Data Unit
  • PPDU PHY Protocol Data Unit
  • a data transmission method using packet aggregation including receiving Media Access Control (MAC) Service Data Unit (MSDUs) including various destination addresses and traffic identifiers from an upper layer; classifying the MSDUs according to each destination address; classifying the MSDUs, which have been classified according to each destination address, according to each traffic identifier; aggregating MSDUs having the same destination address and the same traffic identifier as a MAC Protocol Data Unit (MPDU); aggregating MPDUs having the same destination address from among the MPDUs as a physical (PHY) Protocol Data Unit (PPDU); and transmitting one frame including PPDUs which have different destination addresses.

  • the MPDU includes one MAC header for indicating the destination address and the traffic identifier
  • the PPDU includes one PHY header for indicating the destination address
  • the frame includes a frame header having information for a modulation scheme and a transmission scheme.
  • the hierarchical packet aggregation method of the present invention performs a MAC Service Data Unit (MSDU) aggregation or a MAC Protocol Data Unit (MPDU) aggregation according to each receive terminal, constructs PHY Service Data Units (PSDUs), and attaches a PHY header having transmission scheme-related information appropriate for each receive terminal according to each PSDU, thereby constructing PHY Protocol Data Units (PPDUs).
  • MSDU MAC Service Data Unit
  • MPDU MAC Protocol Data Unit
  • PPDUs PHY Service Data Units
  • the PPDUs constructed in this way are mapped to one radio frame, a frame header is attached to the radio frame, and then the radio frame is transmitted.
  • FIG. 4 illustrates the hierarchical packet aggregation method according to a preferred embodiment of the present invention, which is an exemplary case in which four MSDUs are transferred from an upper layer, for convenience of description.
  • MAC headers are attached to the MSDUs 410, 420, 430 and 440, which have been transferred from the upper layer, according to receive terminals to which the MSDUs are to be transmitted, so that MPDUs are generated. That is, MAC headers 415, 425 and 435 having the same Destination Address 1 (DA1) are attached to the MSDUs 410, 420 and 430 to be transmitted to a terminal #1, and a MAC header 445 having a DA2 is attached to the MSDU 440 to be transmitted to a terminal #2, so that corresponding MPDUs 41 to 44 are constructed.

Then, PHY headers 451 and 461 including information regarding a modulation scheme and a transmission scheme for a corresponding terminal are attached to the PSDU 450 and 460, respectively, so that PPDUs 45 and 46 are constructed.
  • the MPDUs 41 and 42 having the same TID are mapped to the PPDU 45 together with said one common MAC header, and the MPDU 43 having a different TID is mapped to the PPDU 45 together with its own MAC header 435. If there is a situation in which MPDUs having the same DA and TID as those of the MPDU 43 must be mapped to the PPDU 45, it is preferred that the other MPDUs are mapped without MAC headers, i.e., in a state of the MSDU.
  • each PPDU 45 and 46 constructed in this way are mapped to a radio frame 470 of a predetermined length.
  • each PPDU has a modulation and transmission scheme index (M1, M2). Then, a frame header 471 is attached to the radio frame 470 and the radio frame 470 is transmitted.
  • the MPDUs having the same DA are aggregated, i.e., data are aggregated according to each terminal, so that overlapping MAC headers can be reduced and corresponding MPDUs can be transmitted at an optimal transmission rate for each terminal.

  • the MAC header includes information for types of the same DA and TID.
  • the MSDUs having the same DA and TID are aggregated, so that one MPDU is generated.
  • a PSDU is then generated which contains MPDU's having the same DA but a different TID (step S506).

  • packets transferred from an upper layer are hierarchically aggregated according to DAs and TIDs, and aggregated as a data unit according to each destination before being transmitted, so that data transmission can be performed at an optimal transmission rate for a destination terminal, to improve the quality of a real-time traffic service sensitive to a delay.
